Frank thanks for the comments about  scams. The way you describe it is exactly how it happened. I did note that the satisfied customers who downloaded the document had done so in 2020 not 2007 or 2014 as is usually the case when reading old forums. Sorry for posting the link but I am embarrassed to admit that I did not realise that it was a scam. I was saved by the fact that I never post personal details online and only give my CC details to reputable sites such as ebay or Abe Books.

For the record I got my first dial up connection back in 1996 and because I am careful have never been scammed or had any negative internet  experiences. But this shows how careful you need to be..........  Phew!
